yes, it solved my problem, next time I have I problem I'll post here again

*EDIT*
OK, new question;
How can I sort this:

I'm far from being an expert with UVW unwrapping in Blender. So don't expect this answer to be as short and useful as the previous one

When doing unwrapping, I always do it by using "Project from view" (UKEY, choice #5) I do it several times, a subset of each object at a time. Then, you'll have to merge vertices shown twice (because selected twice on two different faces) or more. To do that, use Ctrl+C to activate automate selection of multiply-shown-vertices, then V to merge them. Actually it won't merge them (just place both at the very same location) so you'll have to stick using the Ctrl+C feature (otherwise use Alt+C to stop using it)

Can I import somehow .ter-files in blender?

.ter-files are from Terragen

Don't forget to try using a search engine

Is it possible to "weld vertices within a specific treshold"?
You can select the vertices and weld them together, but that can be time-consuming.

I prefer to make basic shapes with SketchUp (free edition), export them as Ogre .mesh.xml files and import them into Blender.
The drawback is that every polygon seems to get 3 vertices, so auto-welding them back together would be quite usefull.

In the "Editing" panel (F9), box "Mesh tools", there is a setting named "Limit" : the tiptool is self-explanatory : "Specifies the max distance 'Rem Doubles' will consider vertices as 'doubled'". The default value is 0.001, this is expressed in Blender units.

Another useful option is Alt-J while in Edit mode : this feature tries to converse triangles in your mesh to quads. As an example, try to convert a cube to a triangle-only mesh (Ctrl-T) then using Alt-J will get you a cleaned mesh.
